Boltorn™ dendritic polymers Advancing performance & comfort

The cutting edge of technology Whether you are looking to secure firmness in flexible polyurethane foam, improve the Tg/flexibility ratio of cast polyurethane elastomer products, ensure rapid curing and durability in UV curing applications or reduce VOC in architectural coatings, dendritic polymers are a solution. Dendric polymers are characterized by a densely branched backbone and a large number of reactive groups. Their globular structures have excellent flow and processing properties at high molecular weight. The exceptional concentration of reactive groups facilitates customization of...

Boltorn™ dendritic product range Boltorn™ products are produced using polyalcohol cores, hydroxy acids and technology based on captive materials. The dendritic structures are formed by polymerization of the particular core and 2,2-dimethylol propionic acid (Bis-MPA). The base products obtained are hydroxyl-functional dendritic polyesters. Fully aliphatic and consisting only of tertiary ester bonds, they provide excellent thermal and chemical resistance. Extensive branching also improves reactivity, lowers viscosity and results in balanced mechanical properties. Three technology advantages...

Polyurethanes Millions of car owners already enjoy superior seating comfort with the help of Boltorn™ technology. In partnership with a leading automotive foam supplier, we have developed a unique technology that improves the firmness of high-resilience foam articles with dendritic polymer polyols. Products in focus Boltorn™ H311 – for exceptional firmness & stability Boltorn™ P500 – for high firmness at low compression set This liquid polymer polyol provides exceptional compressive loadbuilding characteristics in flexible foam at very low addition levels. It is used as an additive,...

Radiation curing Boltorn™ products enhance radiation curing applications by providing oligomer precursors that significantly increase the average molecular weight of UV formulations at high acrylate concentration. Acrylates based on Boltorn™ technology are typically used to partially or fully replace urethane acrylates, other top-end oligomers or acrylates of high functionality. Oligomer precursors for superior performance Acrylate oligomers based on Boltorn™ dendritic polyols offer significant benefits: • Excellent reactivity • Improved scratch resistance and film hardness For coatings,...

Architectural coatings Product data summary Boltorn™ performance additives for solvent-borne and waterborne architectural coatings help coating formulators comply with environmental demands without compromising coating performance. A number of patented technologies have been developed in which Boltorn™ additives improve the performance of architectural coatings. You can achieve the required coating properties while reducing VOC. Further on, with Boltorn™ you get improved drying in wood stain and reduced cost at lower VOC in water-extended solvent-borne paints. Polyether/ polyester polyols...
